Effect of Camphor Sulfonic Acid Doping on Structural, Morphological, Optical and Electrical Transport Properties on Polyaniline-ZnO Nanocomposites

摘要

In the present work, we report on effect of camphor sulfonic acid (CSA) doping on polyaniline-ZnO (50%) nanocomposites prepared by spin coating method on glass substrates. The XRD analysis revealed that the addition of CSA has no effect on crystallinity of PANi-ZnO nanocomposites. Surface morphological studies (SEM) showed that CSA has a strong effect on morphology of PANi-ZnO. The FTIR & UV-Vis spectroscopy confirmed the interaction between CSA and PANi-ZnO nanocomposite. DC electrical conductivity studies showed an increase in conductivity of PANi-ZnO nanocomposites by one order due to addition of CSA (10% - 50%).
